Testimonials

Cooper K.
Mercury SpitFire X7
I installed the SpitFire X7 on my 75HP outboard, and the boost in performance is incredible! Superb handling and hole-shot.

Hunter R.
SpitFire X7 Fishing Boat
In comparison to the 3-blade aluminum propeller I was using, the acceleration is lightning-fast. My fishing trips are much improved!

Bennett S.
Mercury SpitFire X7
I work for Mercury so I probably shouldn't get the chance to review.. but this propeller is great. Nobody else makes a performance prop for outboards this size.

Kameron J.
SpitFire X7 on Mercury 60HP
I installed the SpitFire X7 on my aluminum fishing boat with a 60HP Command Thrust motor, and I'm blown away by the top speed. Thank you!

Johni P.
4-Blade SpitFire X7 Propeller
When I dinged up my aluminum SpitFire propeller I replaced it with the stainless steel version and it is much better. Same pitch and everything, just all-around better performance.

Mark S.
Stainless Steel Mercury SpitFire X7
I swapped my old prop for the SpitFire X7 on my 115HP outboard, and the change is incredible. The acceleration, handling, and hole-shot have transformed my boating experience.

Whether you’re looking for a replacement prop or want to optimize your boat’s speed, hole shot or efficiency, keep in mind that prop selection is about more than just pitch, diameter and number of blades. Performance is influenced by every aspect of a prop’s geometry, right down to cup, rake angle and edge shape.
